Debug interface mode is initiated by clocking one clock cycle on SWDCLK with SWDIO=1. Due...
Hi,
I was looking at the .map for my project and I noticed that pstorage.c was taking up a bunch of RAM (~600 bytes), which I thought was a lot, so I went into pstrorage_platform...

Hi All
I am doing a BLE based project using nRF51822.Where i need to handle the message [with UUID] by using ble_gatts_char_handles_t.
so, can any one please share information...
I have a central application and peripheral application that are based on the multilink-central/multilink-peripheral examples.
I've modified them to run on the PCA10001...
I have a case where I'm using a timer/counter as a counter with one PPI channel routing a GPIO rising edge to the COUNT task. Another GPIO rising event controls the counting...
I have an nRF52 paired to a central device. In order to delete the pairing on the nRF52 I clear the persistent data (dm_init_param_t).
I notice, however, that even though...
Hi all,
I'm a grad student trying to innovate on the BLE concept. I require a continuous signal as a source: preferably unmodulated, but a long duty cycle could also work...
The NRF52 product specification (aka, datasheet) has 3 chapters in it all relating to TWI: TWI (chapter 49), TWIM (chapter 33), and TWIS (chapter 34).
Which section (TWI...
Hi,
I'm trying to interface SIM808 with nrf51822 over uart using nrf_drv_uart. Everything works well for some time, but then uart starts reporting error code 1, NRF_UART_ERROR_PARITY_MASK...
Hello,
I am working with the GPIOTE library to get a GPIOTE_IRQ from a peripheral.
I have several questions regarding the library and how IRQ works.
1.How do I clear...
Hello,
I am using SDK7.1.0 for NRF51822.
In my subroutine, I would like to disconnect with the peer device, and re-advertise. But when after re-advertising, I found the...
Is it possible to set scope for search in info-center only for SDK 11? It search in all SDK versions and sorts results randomly. It is very annoying. Especially when there...
Hi,
I want to build expertise in BLE and want to use the Nordic nRF51x22 to build a hardware and write the firmware for the same.
I am planning to use the nRF51 DK....
I'm calling sd_ble_gatts_characteristic_add multiple times to add characteristics to a peripheral. At some point I get a return value of 0x200020B6. I'm not making much headway...
Hello everyone,
I am trying to use the ble_app_hrs_rscs_relay example from SDK V11 for s130 (2.0.1).
It compiles and works well when I use an pc10028 evaluation board...
If I have multiple services, 2 for example, how should I set up the srdata.uuids_complete.p_uuids in the code:
